Peer reviewedKehoe, Thomas J. – Environmental Science and Technology, 1977
The instrumental method for detecting total organic carbon (TOC) in water samples is detailed. The method's limitations are discussed and certain precautions that must be taken are emphasized. The subject of TOC versus COD and BOD is investigated and TOC is determined to be a valid indication of biological demand. (BT)

Peer reviewedPhillips, Sidney L.; Mack, Dick A. – Environmental Science and Technology, 1975
This discussion gives a general picture of the instrumentation available or being developed for measuring the four major categories of water pollutants: metals, nutrients, pesticides and oxygen demand. The instruments are classified as follows: manually operated laboratory analyzers, automated laboratory instrumentation, manual field monitors, and…

The procedure and sampler described permits detection of less than 50pg of one polychlorinated naphthalene (PCN) isomer. The method uses gas chromatography-mass spectrometry. The PCNs are collected on a glass fiber filter and two polyurethane foam plugs and extracted with toluene at 25 degrees Celsius. (BB)
